GAS-BURNER.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed May 17, 1917. Serial No. 169,297.

To all whom it may concern:

Be it known that I, JOHN A. FRY, a citizen of the United States ofAmerica, residing at Detroit, in the county of lVayne and State ofMichigan, have invented certain new and useful Improvements inGas-Burners, of which the following is a specification, reference beinghad therein to the accom panying drawings.

This invention relates to burners designed for use in gas stove ovensand more particularly to the construction and arrangement of burnersemployed in gas ranges or the like, and in which the oven burners are ofthe type in which there are a plurality of separately controlledsections.

In gas ranges of this type it is desirable to provide means whereby thisburner, as well as all of the open-top burners of the range, can becontrolled from the front thereof, all of the controlling valves beingpreferably arranged in alinement.

The present invention contemplates an improved construction whereby theseparately controlled burner sections are cast or otherwise formedintegral and preferably provided with integral oflset or bent sectionswhich project through the oven wall and areprovided with means forcoupling the burner sections to the branch pipes leading from the gassupply; to provide an integral forward extension of the burner sectionswhich will facilitate the lighting of the burner, this extension alsoforming a brace member between the sections; to so construct and arrangethe parts that the gas cook or valve controlling the front section alsocontrols the lighter extension, this avoiding the necessity of separatelighting mechanism and control valves therefor; to provide a burnerconstruction of the character above referred to which can be employed ingas ranges having the oven located either at the left or right of theopen-top section; to provide a burner construction which can beeconomically manufactured and easily attached in place or, removed; andin general to provide a new and improved burner construction for rangesor the like In the drawings:

Figure 1 is a top plan view partly in section of a gas range embodyingmy invention;

Fig. 2 is an enlarged perspective view of the oven burner construction;

Fig. 3 is a cross-section on the line 8-3 of Fig. 1;

Fig. 4 is an enlarged cross-section on the line 4-4 of Fig. 1;

Figs. 5 and 6 are enlarged detail views of the clamping plates for theoven burner section;

Fig. 7 is a cross-section on the line 77 of Fig. 1.

Fig. 8 is an enlarged fragmentary perspective view of the clampingplate.

In detail A designates a gas range having an open-top section B. and anoven section C located at one side of the open-top section. A pluralityof burners D, D, D D and D are provided for the open-top section, theseburners being connectedto the gas supply pipe E through branch pipescontrolled by suitable gas cocks or valves F, F, F F and F The ovensection C is provided with a burner G formed of separately controlledfront and rear-burner sections G and G preferably connected by anintegral section G which is in communication with the interior of therear section G but has no interior communication with the front burnersection G. The burner construction is also provided with a forwardlyprojecting lighter section G which extends to a posi tion near the ovendoor. The portions G and G of the oven burner are independently suppliedthrough branch pipes controlled by gas cocks or valves J and Jrespectively, these valves being located at the front of the range, andpreferably in alinement with the valves F, F, etc. of the opentopsection.

When it is desired to light the oven, the valve J controlling the frontburner section G is opened. This also provides a flow of gas to the jetsJ of the lighter G. The flame then passes back along the lighter andignites the gas flowing from the jets in the front burner section G. Thecontrol valve J is then opened and the gas passing through the rearburner section G also extends into the section G which has a row of jetopenings J extending forward to a point of proximity to the section G.The flame will thus be carried back along the section G to the rearburner G If it is desired to light only the rear section the operationis the same except that the valve J is closed after the rear burnersection has been lighted.

In manufacturing of stoves, ranges or the like it is customary to formgas ranges of this type with the oven located either at the right or theleft of the open-top section. To avoid the necessity of providingdifferent constructions of oven burners for the different locations ofthe oven with reference to the open-top, I have provided a novelarrangement and mounting of the oven burner section whereby it can bereversed from the position shown in Fig. l and employed on a range wherethe oven is located at the left of the open-top section. Also this ovenburner section is so constructed that while the burner sections G and Grare independently controlled, they can be integrally formed andassembled as a complete unit.

In the particular construction shown the rear burner section G isprovided with a portion extending through the oven wall L and benttoward the front. The front burner section G also has a portion K eX-tending through the oven wall L and bent toward the front. This lastprojecting portion K is relatively short so that both sections K and Kpreferably terminate adjacently. Near their front they are connected byan integral cross bar M and their ends are suitably threaded to receivecouplings N and N by which they are connected to the branch pipes O and0.

As shown in detail in Fig. 4; the burner sections G and G are providedwith ridges Q, Q, Q and Q4 the ridges Q and Q being located in the tophalf of the burner and the ridges and Q on the lower half. Vilhere theburner is used with an oven located at the right of the open-top, asshown in Fig. 1, the gas jets Q are drilled or otherwise formed throughthe ridges Q and Q. If, however, the burner section is employed with arange having the oven located at the left the gas jets are formedthrough the ridges Q and Q5 Thus the same construction can be employedwith either location of the even by simply reversing the position of theburner sections to extend either to the left or to the right of thebranch pipes O and 0. Also it will be noticed that this arrangementpermits the employment of similarly formed branch pipes O and O and theentire construction is standard for either location of the oven. Attheir free ends the burner sections G and G are provided with bearingportions R and R which rest in seats R and R formed in a bracket R whichis bolted to the oven wall, this bracket being also interchangeable. 7

To facilitate the assembling of the burners, the oven wall L is formedwith a relatively large opening L through which the projecting ends ofthe burner sections G and G extend. To attach the burners to the ovenand rigidly lock them in'place, there are preferably employed clampingplates 5 and T. The clamping plate S, which fits on the outer wall ofthe oven, is formed of two sections S and S as shown in Fig. 5, whilethe inner clamping plate T is similarly formed of sections T and T asshown in Fig. 6. Each of these sections S and S and T and T 2 havesemi-circular seats U which cooperate to fit snugly around the portionsof the burner sections which project through the wall. The section Salso has a lug S which overlaps a similar lug S on the sections whilethe sections of the clamping plate T are provided with similaroverlapping lugs T and T 2 Bolt holes S and T are formed in theseoverlapping lugs and receive the clamping bolt W. When the wing nut V onthis bolt is tightened up the parts will be locked in rigid position andit is obvious that the same clamping plates could be employed where theoven is located at the left hand side of the open-top as where it islocated at the right.

The oven burner, as above described, can be cast or otherwiseeconomically formed, and as it is a unit construction can he quicklyattached and detached from the oven. Also it involves theinterchangeable feature above described, although the invention is notnecessarily limited to the details of construction set forth.

What I claim as my invention is:

1. The combination with an open-top section and an oven section adjacentthereto, of a gas conduit extending along the front of said open-top,and a burner for said oven, comprising an integral construction havingburner sections terminating in supply connections leading toward saidgas conduit and extending through the wall of the oven into the plane ofsaidopen top section, and a mounting for said burner sectionsconstructed to hold the same in ovens located at either side of theopen-top section.

2. The combination with an open-top section and an oven section adjacentthereto and having an apertured wall, of an oven burner comprising aplurality of burner sections having forwardly bent portions positionedexterior of the oven, and a clamping plate for said burner comprising aplurality of plate members formed in sections, and a clamping member forlocking said sections in position.

3. A gas burner blank, comprising a tubular member having longitudinalridges at opposite sides thereof for alternative use for jet openings,according as the blank is used in a right handor left hand oven.
